Abstract— In this modern world Smartphones and Tablets are need for every group from Children, teens, Parents, Business executives,
Professionals to old age people. With this techy gadgets, location based applications are widely used as it makes life very easier, faster
and keeps track of our near and dear ones as well as our business associates. The SMART Travel Alarm is designed to provide high tech
services to users based on the information of their current geographic locations. Some of these services include “Reached to destination
alarm”, Email someone on reaching the destination etc. In this paper we illustrates the development of SMART Travel Alarm - a
Android application based on Sencha 2.2 framework using Google Web Services to offer multiple services to the users on the move. The
developed app works perfectly fine on major smartphones and tablets running on various versions of android OS.
Keywords— Smart Travel Alarm, Android application, Sencha 2.2 framework, Smartphones, Tablets.
I. INTRODUCTION
The proliferation of mobile platforms and technologies,
along with the evolution of smart devices, provide plenty of
opportunities for compelling applications. The key expectations
are multifold, and include cost effectiveness, a single code base
to work across multi platforms, an outstanding UI and faster
delivery cycles. The modern applications are taking full
advantages of the device features (GPS, camera...), form
factors (tablets) and appealing user interaction. The best fit to
accommodate most of the key mobile capabilities (single code
base form factors, great UI) is to adopt mobile web
technologies. This can be augmented by using the Android
approach to take full advantage of the device features in
addition to the benefits listed above.SMART Travel Alarm is
such aAndroid application which is developed on Sencha 2.2
framework. Sencha Touch enables us to quickly and easily
create HTML5-based apps that work on mobile devices, and
produce a native-app-like experience inside a browser or in
aAndroid shell. Sencha Touch supports Android, iOS,
Windows Phone, Microsoft Surface Pro and RT, and
Blackberry devices.
If we implement it by designing a separate hardware it will
add extra cost to the end user so we thought to implement on
the commonly available device with everybody, Yes that‟s
Smartphone and Tablet! which also have built in GPS. But if
we use GPS continuously then the device will run out of juice
quickly. Also everybody may not be using same Smartphone
with same operating system and versions. So we have the
following problems to address:-
II. PROBLEM DEFINITION
Our solution was to develop an Alarm that could interpret
GPS coordinates and had a program in it to ring and vibrate to
wake the user up. It had to be completely portable, with a
portable power source, and preferably fit into a pillow, while
remaining comfortable. It also had to be easy to use and easy to
replace batteries. Its design and advanced implementation
allows us to save every volt of our smartphone.
There are many instances where we may want an alarm
clock that doesn't ring at a set time, most notably, travel. Trains
and planes get delayed, cars run into traffic, and it would be
convenient if the alarm would ring when we arrived at our
destination, not when we were supposed to arrive.

iv.
Design and develop the Smart Travel Alarm for
Smartphones and Tablets.
The application design should be smart enough to be
implemented on almost all the Smartphones and
Tablets running on most of the operating systems and
their various versions.
Propose and implement the logic to save the battery
consumption from the GPS usage.
The application should send a SMS and an email to
the relatives or other intended persons.

Along with alarm, user can optionally put the
reminder text as well.
Once user is near the location, the alarm will ring and
also if there is any reminder text it will be displayed to
user.
User can edit/delete/update/enable/disable the alarms.
User can see the locations on Map to find out how far
he is from the expected location.
IV. SYSTEM ARCHITECTURE OF SMART TRAVEL ALARM
SMART Travel Alarm is a mobile application that has the
capability to provide real time information based on the user's
current location. GPS interaction module is the heart of
SMART Travel Alarm, which has been developed, will act as
collection centre, storing and supplying the geographical data
for being manipulated by the application. Data which stored at
the system will be used within making the decision process as
per the logic explained below. Through this application, data
will be collected to trace every unit location and every unit also
can update any additional information. This module integrates
hardware, software and data for capturing, managing, analysing
and displaying all forms of geographically referenced
information. The architecture of the SMART Travel Alarm
consists of several segments that are needed to create a fully
functional unit.

Display module: In this module the, the Google map is
displayed the locations using the GPS and
GPRS/3G/Wifi networks available in the Smart
phones. By using this module the user can set their
destination and current location based on their needs
of travel.

GPS interaction module: In this module the GPS
interaction (i.e. the location update is changed based
on their users time limit. And check whether the GPS
and the internet provider is enabled or disabled. Based
on that the alert will shows to the android notification
bar in android device.

Place management module: In this module the
location details are stored in SQLite data storage
within the android device. i.e. The visited location
details are getting from the location updates and stored
in SQLite data storage for the user future reference.
Ring tone module: This is the Settings module, the
default five ringtones are stored within the application
and also the ring tone chooser based on their user need
from their Audio gallery. And also it has the volume
control and vibrates mode control settings in this
application module.

Figure 1: Logic of the Smart Travel application
It works with GPS but also with Network, selecting the best
location on each moment. If we don't move it does not consume
our battery checking our position. The application “SMART
Travel Alarm” solves all these problems. It offers below
services:

Retrieves the user‟s current geological coordinates.
Allow user to enter new alarm for a particular location

Alarm module: This is main module of this project; in
this the alarm service and location updates are done
using the android Background services. The location
updates is done by using the GPS and Internet
providers. And the alarm is set using the android
device alarm services.

Feature Selection Module: From this module user can
use the features available in the system.
V. IMPLEMENTATION & METHODOLOGY
Dr. Abhilasha Mishra#1 IJECS Volume 3 Issue 7.Month July 2014 page no. 7156-7162
Page 7157

The purpose and functionality of SMART Travel Alarm
application is to provide the information available to their user
when they arrive at certain location. GPS is becoming popular
with location positioning system, today there is huge demand
of location based applications. In a SMART Travel alarm
system we provide an alert when user reached the destination
or any famous spot in city to provide knowledge and
information of mobile user‟s current location. Google Places
API is a service that provides service information about places,
spatial locations, geographic locations, places of user‟s choiceusing http requests. User can get places request/response
specifies locations as latitude and longitude coordinates. We
use these API for implementing our application.
Profiles: enable Us to easily customize Our app's UI
for tablets and phones, while sharing as much code as
possible.
VII.
FUNCTIONAL ANALYSIS
There are some places API are available:





Place Searches- It returns an array of places based on
search string or locations defined by user.
Place Details- this request returns detailed information
about specific place including user reviews.
Place Actions- user can schedule events, add or
remove places.
Place Photos- user can request for places related
photos stored in Google‟s place database.
Places Autocomplete- It provides autocomplete
functionality to user for text based searching of
geographic location by returning places a user type.
VI. ANATOMY OF THE ANDROID APP BASED ON SENCHA 2.2
An app is a collection of Models, Views, Controllers, Stores,
and Profiles, plus additional metadata for app-related entities,
such as application icons and launch screen images.
Application indicates an instance of Ext.application, whereas
application or app is the program we are coding.
Figure 3: Home Screen
Figure 3 is the Home screen for SMART TRAVEL ALARM
application which will be displayed once user launches the
application. In Menu list user can see three options i.e. Map,
Saved Locations and Settings. When user taps on component
no. 2 it displays the map of Our current location if GPS in ON.
User is able to search the location in component no. 6.

An SMS can be send automatically to traveller
relatives or intended persons, give information if user
reach the specified destination.
The application user would be able to store locations
on which alarm was previously set so that he/she can
use it later.
The application user would be able to set the vibration
control option which will vibrate when user reaches
the destination. This feature will help the dumb and
deaf travellers a lot as they can‟t speak and hear but
they can feel the vibration sense.
The application user can set the ringtone as per his/her
choice from the ringtone control option available on
the settings screen.
The application travel has implemented with logic to
save the power consumption by the GPS of the phone.
It initially gets the location coordinate from the
service provider network and will turn on GPS only
when destination is near (example 5km) so as to give
more precise location.
The application is loaded with a feature to provides
minimum distance on which user want to trigger alarm
(example before 2 km)
The application allows users to edit details of the
already set locations.
The application allows users to delete option for
stored locations individually or all of them in one go.
The application can be configured to enter the
username of the traveller so that they can be tracked
uniquely from the SMS and Email confirmation.
provides a cost-effective solution for a very wide range of
downloadable app types and allows gradual entry into the
new world of HTML5 while future-proofing your
investment.

IX. CONCLUSIONS
Thus we conclude the implementation of SMART Travel
Alarm through Google Web Services and Google APIs on
Smartphones and Tablets offers multiple services to the
users based on their location. We have overcome the
problem statement as defined earlier. With Sencha 2.2 its
easy to develop the Android app which runs on all the
versions of Android and on various devices of different
screen size and resolution.
All the leading smartphones and tablets have very powerful
HTML rendering engines, which already support most of
the upcoming HTML5 and CSS3 standards. JavaScript
toolkits like Sencha Touch are fully compatible with the
Android app development model, making it easier to
achieve a look and feel that is often indistinguishable from
native. As a result, Android apps running on mobile devices
with reasonably modern hardware can achieve highly
interactive and impressive user interfaces using just
HTML5, CSS3 and JavaScript.
For those cases where your app does require special
graphics or system-level interaction that cannot be achieved
with HTML, Android apps can combine web pages with
native ones. Other organizations are developing Android
apps, while planning to turn them into HTML5 web apps in
the future without having to rewrite them from scratch.
From a strategic point of view, development organizations
should seriously consider adopting HTML for mobile app
development sooner rather than later. The Android app
model, although not suitable for all app development needs,
